3 Claims.

sides to other grinding and polishing tools,

whereafter the stones are removed from their 15 molds to expose their inner ends to. grinding and polishing tools grinding and polishing one side of the stone to be turned to expose their other side to other grinding and polishing tools and finally to be removed from their molds and col- 2 lected.

Another object of my invention is the provision of a rhinestone manufacturing machine in which the molds are. provided with spring controlled plungers, operated by cams to carry the 25 mold parts against one another and to separate them after the molding operation.

Stillanother object of my invention is the provision of a rhinestone making machine equipped with containers for sealing wax kept 30 in liquid condition to secure the stones in their molds.

A further object of my invention is the provision of a rhinestone molding machine in which the stones are ground and polished on one side 35 and equipped with special turning devices to expose their other sides to other grinding and polishing tools.

A still further object .of my invention is the provision of a rhinestone producing machine 40 equipped with means for removing the ground and polished stones from their molds into other molds to expose their inner ends to grinding and polishing tools for grinding and polishing one side of the stones turning the same and exposing them to other grinding and polishing tools for finishing the stones whereby means are provided to remove the finished stones from their molds and collect the same.

These and other objects and advantages of 50 my invention will become more fully known as the description thereof proceeds and will then be specifically defined in the appended claims.

In the accompanying drawings forming a material part of thisdisclosure:

Fig. 1 is a side elevation, partly in section of a rhinestone producing machine constructed according to my invention.

Fig. 2 is a fragmentary top plan view thereof.

Fig. 3 is a detail sectional view of the mold- GU ing and connecting elements used in my machine on their conveyor chains and on a somewhat enlarged scale.

Fig. 4 is a section on line 44 of Fig. 3.

Fig. 5 is. a fragmentary detail top plan view of the molds and their conveyor belt.

Fig. 6 illustrates the grinding and polishing of one end of the stone and the turning and grinding and polishing operation of the other end of the stone in their successive order.

Fig. 7 is an end view seen on line 'l-I of Fig. 6.

Fig. 8 is a sectional side elevation of the mold turning member.

Fig. 9 is a top plan view thereof seen in the direction of arrows 9--9 of Fig. 6.

Fig. 10 is a section through the mold turner on line Ill-l0 of Fig. 6.

As illustrated, the material from which the rhinestones are to be made, preferably glass is deposited ina crucible Ill heated by the gas flames l l of burners l2 supplied with gas through a conduit l3.

The molten glass l4 within a basin i5 is discharged through a tube 16 having suitable discharge openings I! in the bottom, into the halfmolds l8 onan endless conveyor i9 of suitable well-known construction, guided over the feed rollers 20, 2| rotated from any source of power. Above the conveyor l9, another-conveyor 22 is arranged carrying a plurality of half molds 23, supplementing the half mold l8, and provided at the ends of plungers 24 adapted to be depressed against. the action of the springs 25 Wound about the plungers 24 between their heads and the conveyor, by means of acam 26 attached to a machine part. The cam will pres: mold half 23 into mold half i8 to form the stone as indicated at 21 in Fig. 3. After plunger 25 has passed cam 26 its spring will raise plunger 25 and mold 23 so as to leave the molded stone in form It! as shown at 28, in Fig. 3.

Belt or conveyor 22 is guidedovertthe sprocket wheels 29, 30, driven in the 'usual well-known manner from any suitable source of power.

A third conveyor 3| is arranged in juxtaposition to conveyor l9 and is guided over wheels 32, 33, and carries the half molds 34 on the lower ends of plungers 35 having springs 36 wound about their shafts between their heads and the conveyor. The molds 34 are guided past a brush 31 or similar member revolving in a tank 38 filled with molten sealing wax 39 or the like substance to cover the interior of molds. 34

with this substance, which to insure its holding through -a gas flame of grinding wheel 42 having the form clearly illustrated in Fig. 7, and a polishing wheel 48, on shafts 44, 45, rotated from any suitable source of power.

The grinding wheel 42 and the polishing wheel 48 having done their work and ground and polished one side of the stone 28 held in mold 34, it now becomes necessary to turn the stone in its seat to grind and polish its other side also. This is efiected by the mechanism illustrated in Figures 8, 9 and 10, in which a cross 45 on a spindle 41 engages the mold 34 asshown in Fig. 9.

The spindle 41 enters with its lower end a casing 48, in which it carries a roller 48 provided with depressions 50 adapted to be engaged by the conical inner end 5! of a plunger 52 having at its outer end a rod 53 attached thereto about which a spring 54 is wound within casing 48 between plunger 52 and a plug 55 closing the lower end of casing 48, and the plunger can be operated by a handle 55 to turn the stone to expose its other side to the grinder 51 on shaft 58 and thereafter to a polishing tool 59 on shaft 50.

As shown in Fig. 1, a fourth conveyor 5| running over wheels 52, 53, driven from any suitable source carries molds 64 havingspring controlled plunger rods 55 past a brush 65 or the like within a casing 51 filled with a molten'sealing wax 58. If now the conveyor carries the molds 54 in front of the ground and polished stones on conveyor 3! to which conveyor 5| is rectangularly disposed, the plungers 55 will be engaged by a cam 59 and pressed against the action of their springs against the stone 28 in mold 34 and the sealing wax in the same which has become cold and brittle will release the stone and the same'will adhere to the mold 54 and carried by the conveyor forth to the grinding and polishing wheels 15, II, respectively to polish one side of the stone, whereafter the same is turned lg agdevice similar to device illustrated in 8- The conveyor 5| then carries a stone to another grinding wheel I2 and a polishing wheel I8 whereafter the finished stone is removed from 45 the mold by the engagement of a suitable tool 14, to be collected in a suitable receptacle.

The operation of my machine will be entirely clear from the above description by simultaneously having reference to the drawings. The

5 glass is melted in a suitable crucible and then,

the molten mass is deposited into the half molds successively carried by a conveyor to the .discharge opening of the crucible.- A cam 25 will press the supplementary molds on asecond conveyor for molding the stone into the half mold, as illustrated in Fig. 3 and after passing the cam, the springs of the plungers will withdraw the plunger of the supplementary mold from the half mold holding the stone. A

" veyor provided with molten sealing wax which is kept semi-liquid will be carried in front of the half mold with the stone exposed and encounters a cam to press the molds provided with-sealing wax against the stone which will now adhere to said mold to be carried successively to a grinding and polishing, roller to grind. andpolish one side of the stone. Y

The molds are then turned by a special device to expose their other side to other grinders and polishers.

.A fourth conveyor, angularly disposed to'the third conveyor brings other molds having spring controlled plungers in front of the ground and I polished stones ands. cam engaging the plungers Other plunger controlled molds on a third conr.

will press the molds provided with fresh sealing wax against the stones in the molds on the third containing the wax which has become brittle and will take the stones along and carry the same to other grinding and polishing rollers for grind ing and polishing one side of the stone. Thereafter another mold turning device will turn the of the minor details thereof as come within the scope of the appended claims, without departure from the spirit of my invention, and the principles involved. i

Having thus described my invention, what I claim as new, and "desire to secure by Letters Patent is:

1. A rhinestone producing machine comprising a means for forming the stones from molten.
